The half lives of two radioactive nuclides A and B are 1 and 2 min. respectively . Equal weights of A and B are taken separately and allowed to disintegrate for 4 min. What will be the ratio of weigths of A and B disintegrated ?

A

`1:1`

B

`5:4`

C

`1:2`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
B

Ratio of A B disintegrated
`(15)/(16)x : (3x)/(4) implies 5:4 `
